An apparatus for implementing a lane change decision aid system (LCDAS) includes: a sensing unit sensing whether there is a target vehicle in adjacent zones, a rear zone, or a forward zone of a subject vehicle; a determination unit determining an activation condition for determining whether an LCDAS function is active/inactive and a warning condition for determining whether a warning of the LCDAS function is issued/un-issued, based on the sensing of the sensing unit; a warning unit issuing the warning to a driver based on the determination of the determination unit; and a control unit controlling the sensing unit, the determination unit, and the warning unit.
Legal claims defining the scope of protection, as filed with the USPTO.
4. The LCDAS apparatus of claim 1, wherein the controller outputs a speed control command controlling the speed of the subject vehicle or a steering control command controlling a steering of the subject vehicle, corresponding to an issuance of the blind spot warning, an issuance of the closing vehicle warning or an issuance of the forward vehicle warning.
5. The LCDAS apparatus of claim 1, wherein the controller outputs a control command decelerating the speed of the subject vehicle corresponding to the low warning level and outputs a control command decelerating the speed of the subject vehicle and a control command controlling the steering of the subject vehicle to be an opposite direction to the target vehicle, corresponding to the high warning level.
6. The LCDAS apparatus of claim 1, wherein the warning level evaluation condition further includes a subject vehicle lane location evaluation condition, and a lateral clearance evaluation condition.
11. The LCDAS control method of claim 7, wherein the warning level evaluation condition further includes a subject vehicle lane location evaluation condition, and a lateral clearance evaluation condition.
